Algebraic reconstraction for 3D magnetic resonance-electrical impedance tomography (MREIT) using one component of magnetic flux density
(Institute of Physics and Engineering in Medicine, 2004)Magnetic resonance-electrical impedance tomography (MREIT) algorithms fall into two categories: those utilizing internal current density and those utilizing only one component of measured magnetic flux density. The latter ... -
Algorithms for effective querying of compound graph-based pathway databases
(BioMed Central Ltd., 2009-11-16)Background: Graph-based pathway ontologies and databases are widely used to represent data about cellular processes. This representation makes it possible to programmatically integrate cellular networks and to investigate ... -
Assessment methods and how teachers and students view them in a computer science course at Uppsala University
(ACM, 2010)I have examined concepts of assessments and aimed to see differences between teachers and students opinions. I created a questionnaire and sent it to three groups in CS department at Uppsala University. These groups were ... -
ChiBE: interactive visualization and manipulation of BioPAX pathway models
(Oxford University Press, 2010-02-01)SUMMARY: Representing models of cellular processes or pathways in a graphically rich form facilitates interpretation of biological observations and generation of new hypotheses. Solving biological problems using large ... -
Content-based retrieval of historical Ottoman documents stored as textual images
(IEEE, 2004)There is an accelerating demand to access the visual content of documents stored in historical and cultural archives. Availability of electronic imaging tools and effective image processing techniques makes it feasible to ... -
Environmental efficiency in carbon dioxide emissions in the OECD: a non-parametric approach
(Academic Press, 2000)The role of the environment is an important issue in the policy-making and hence, the accurate assessment of the environmental conditions is vital. In this paper, an environmental efficiency index is developed for the OECD ... -
Grace periods in sovereign debt
(Wiley-Blackwell Publishing Ltd., 1999)This paper presents a theoretical analysis of grace periods in the context of an overhang of external debt creating a tax on domestic investment. The grace period arises as a Nash equilibrium strategy of the creditor in a ... -
A hybrid classification model for digital pathology using structural and statistical pattern recognition
(Institute of Electrical and Electronics Engineers, 2013)Cancer causes deviations in the distribution of cells, leading to changes in biological structures that they form. Correct localization and characterization of these structures are crucial for accurate cancer diagnosis and ... -
Identification of parametric policy options for rehabilitating a pay-as-you-go based pension system: an optimization analysis for Turkey
(Routledge, 2001)Publicly managed pension systems operating on the basis of pay-as-you-go (PAYG) schemes face financial difficulties worldwide. The expenditure-revenue balances of such a system are determined jointly by the selected ... -
Increasing the effectiveness of time-use survey with qualitative methods: the analysis of time-space interaction
(Routledge, 2010-03)Time-use surveys have been rich data sources in many countries for a long time. Turkey was among the countries that realized the potential of time-use surveys quite late and completed the first national survey in 2006. ... -
Instrumental neutron activation analysis of blood serum
(Kluwer Academic Publishers, 1995)Instrumental neutron activation analysis has been used to determine 15 trace elements in twelve blood serum samples taken from healthy students at Bilkent University in Ankara. The method allowed the determination of Sc, ... -
Integrative analysis of complex cancer genomics and clinical profiles using the cBioPortal
(American Association for the Advancement of Science (A A A S), 2013)The cBioPortal for Cancer Genomics (http://cbioportal.org) provides a Web resource for exploring, visualizing, and analyzing multidimensional cancer genomics data. The portal reduces molecular profiling data from cancer ... -
Isomeric yields of130Sb, 132Sb, 134I, and 136I in the thermal neutron fission of235U
(Kluwer Academic Publishers, 1992)Isomer yield ratios of130Sb,132Sb,134I and136I isomers formed in the thermal neutron fission of235U have been calculated from our previous experimental studies that led to the identification of these species. In those ... -
Magnetic resonance electrical impedance tomography (MREIT) based on the solution of the convection equation using FEM with stabilization
(Institute of Physics Publishing, 2012-07-27)Most algorithms for magnetic resonance electrical impedance tomography (MREIT) concentrate on reconstructing the internal conductivity distribution of a conductive object from the Laplacian of only one component of the ... -
Measuring exchange rate misalignment in Turkey
(Routledge, 2004)Turkey has embarked an extensive dis-inflation and stabilization program in December 1999. The programme exclusively relied on a nominally pegged (anchored) exchange rate system for dis-inflation and on fiscal austerity. ... -
Money demand, the Cagan model, testing rational expectations vs adaptive expectations: the case of Turkey
(Springer, 1999)This paper estimates the Cagan type demand for money function for Turkish economy during the period 1986:1-1995:3 and tests whether Cagan's specification fits the Turkish data using an econometric technique assuming that ... -
Negative phase advance in polarization independent, multi-layer negative-index metamaterials
(Optical Society of American (OSA), 2008)We demonstrate a polarization independent negative-index metamaterial (NIM) at microwave frequencies. Transmission measurements and simulations predict a left-handed transmission band with negative permittivity and negative ... -
Optimization of the gain-bandwidth product of capacitive micromachined ultrasonic transducers
(IEEE, 2005-12)Capacitive micromachined ultrasonic transducers (cMUT) have large bandwidths, but they typically have low conversion efficiencies. This paper defines a performance measure in the form of a gain-bandwidth product and ... -
A photometric investigation of ultra-efficient LEDs with high color rendering index and high luminous efficacy employing nanocrystal quantum dot luminophores
(Optical Society of America, 2009-12-24)We report a photometric study of ultra-efficient light emitting diodes (LEDs) that exhibit superior color rendering index (CRI) and luminous efficacy of optical radiation (LER) using semiconductor quantum dot nanocrystal ... -
The possibility of theorising the law as a normative social phenomenon: the prior phase and theoretical presuppositions
(Bilkent University, 2019-05)For the last two decades, there has been an impasse between the two main camps of positivism and normativism in the ongoing methodology debate in jurisprudence. Furthermore, there have been recent attacks on the foundations ...
